Optimisation procedure for choosing Cam clay parameters

This paper analyzes the application of a grid-search approach for the estimation of modified Cam clay parameters from triaxial tests. By means of the systematic sampling of the error, in addition to locating the area presenting the smallest error, its “roughness”, is also characterized. This is a valuable information to evaluate the quality of the identification that has been carried out. The methodology proposed here does not aspire to be “the solution” to the problem of parameter identification. The aim is simply to provide a tool which may aid users with criteria.
